My invention relates to mechanism, actuated b a movable part of theadding machine i'or causing the printing in red inl; of the first itemof a column which is totalized.

' It has long been the practice to so print the total at the foot of thecolumn, and also sub-total in the column, but the means heretofore usedfor such purposes will not accomplish'johe printing of the first item inred. By my improvements the added numbers are comprised between andsegregated by a first and last number, both printed in the same color,which is different than'the color of the other added numbers. Suchsegregation or bounding of a series of added numbers is ver f plain tothe eye, and is of practical use an importance.

My invention is adapted for use on the Add-Index machine, and on variousley-set machines on which the adding and printing devices are actuatedby a sidehand crank or by a ,motor, and in which the accumulator as aWhole is movable into and out of engagement with the actuators. Withsuch objects in view as well as other advantages Which may be incidentto the use of the improvements, the invention consists in the parts andcombinations thereof hereinafter set forth and claimed, with the undll:- standing that the several necessary eleme its constituting the samemay be varied in proportions and arrangement without departing from thenature and scope of the invention.

In order to make the invention more clearly understood there 'are shownin the accompanying drawings means for carrying the same into practicalefliect, without limiting the improvements, in their useful appli-Serial No. 55363268.

frame rearward so that its pinions are completcly disengaged from theirtoothed actu ators. The accumulator mechanism comprises numeral whcels 3which are independently rotatable on a shaft 4 in the usual manner. Eachwheel 3 has attached to it a pinion 4 which will mesh with its toothedactuator 5 when the frame 1 is in its forward position, and will bedisengaged from the actuator when said frame is in its rearwardposition. Each wheel 3 also has attached thereto a disk 6 formed with anotch 7, these notches being arranged in a known manner relative to thezeros of the wheels so that when the wheels are all at zero, the notches7 will be in line across the machine and opposite to correspondingrearward projections 8 fixed on a bar or bail 9 carried by a pair or"arms 10, one at each side of the accumulator frame and pivoted theretoat ll. A stop pin (not shown) on the main frame, encountered by theforward edge of either of the arms 10, will hold the projections 8 clearof the accumulator when theaccumulator is in its forward position. Thearrangement is such that when there is nothing accumulated, and thenotches 7 are alined, and the accumulator frame is swung rearward, the

presence of said notches will leave the projections 8 and bail 9stationary, but if any numeral wheel is not at zero, that is to say ifany figure has been accumulated, the edge of the disk 6 of said wheelwill press backward its engaged projection 8 and the bail 9.

12 is a pawl pivoted at 13 to the arm 14 of a lever 15 and formed with anotch or slot 16 which may embrace and which may be disengaged from apin 17 fixed on an arm of a lever 18. The lever 18 is pivoted at 19 t0the adding machine frame plate 20 and has a pin 21 which extends outwardthrough said,

plate. A spring 23 connects said pin with the pawl 12 in-such manner asto press the pawl against the pin 17.

24 is an inking ribbon, having a blue upper part and a red lower part,and passing horizontally across the rear part of the machine betweenthetype and the paper in a known manner, and supported and guided betweenfingers 25 of vertically slidable plates 26, 26. These plates have fixedthereon pins 27 which extend forward and are guided in slots 28 formedin vertical plates 29 fixed to the frame of the machine. Pins 30 fixedon the plates 26 extend forward and through slots 30 in the fixed platesand engage loosely in laterally bent forks 31 of the levers 18. Only oneof these levers is shown, but it will be understood that each of theplates 26 will have a set of the above described parts 12, 15 and 18arranged as already described.

Now when the bail 9 is pressed backward as described, by the edge of oneor more of the disks 6, it will press the pawls 12 rearward anddisengage them from the ,pins 17, 'so that when the lever 15 is turneddownward by the rocking of its shaft 32 by the link 33, it will causethe pawls to slide idly on the bail 9 out of engagement. with the pins 7and the ribbon will not be shifted and will print with the usual bluecolor. But if the number wheels are all at zero the notches 7 will allembrace the projections 8 and leave the bail stationary and the pawls 12in engagement with the pins 17. Under such conditions the levers 15will, when the shaft 32 is rocked backward (which is done by suitableconnections of the link 33 with the adding machine crank handle) causethe pawls 12 and levers 18 to elevate the plates 26 and the ribbon, sothat the lower red part of the same will aline with the type and thefirst'item will be printedin red.

It will be understood that the particular colors which I have mentionedare only typical of any colors which are suitable for the purpose.

The shaft 32 and lever elements 18 are actuated at every movement of theadding machine crank handle.

I do not claim broadly the printing of a special character at thebeginning of a. computation as I am aware that that has been done, nordo I claim mechanism for that purpose, and I do not claim broadly anymeans for shifting the ribbon; but I believe that I am the first toprovide means whereby the accumulator and parts connected therewith arecombined with a shiftable ribbon and control the position of the latter.

The means for moving the accumulator are illustrated only by the pivotedframe 1 which is swingable rearward and forward on its shaft or journals2. This frame is so swung by the usual crank handle of the machine whichis common in this class of key-set adding machines, ever since the timeof the Burroughs Patent 504,963, of September 12, 1893, this being awell known movement used in practically all machines today. Theparticular connections between the crank handle shaft and theaccumulator frame are various in different makes of adding machines, andany suitable means for imparting movement from the crank handle to theaccumulator frame may be employed with my present invention. In myPatent 1,639,923 this crank shaft is shown, together with a yieldingmechanism whereby movement is imparted by the sector to the addingmechanism including the usual toothed actuators, accumulator frame andprinting mechanism (if any).

The printing operation, in which my unshiftcd or shifted ribbon takespart, does or can take place while the accumulator is out of engagementwith the actuators or racks 5.

\Vhat I claim is:

1. In an adding and recording machine the combination of a movableaccumulator having numeral wheels, means for actuating the same, notcheddisks connected with said numeral wheels and having their notches inalignment when the numeral wheels are all at zero, a movable ribbonholder and shifter, means for moving said ribbon shifter to bring adistinctively inked part of the ribbon to printing position, and devicescontrolled by said notched disks for disabling said ribbon shiftingdevices excepting when the numeral wheels are at zero.

2. In an adding and recording machine the combination of movableaccumulating mechanism, notched disks turning with the rotary parts ofsaid mechanism, a bail having means to engage in said notches, a movablesupport for a two-colored ribbon having upper and lower portions ofdifferent colors, a pawl adapted to actuate said ribbon support andarranged in the path of said bail to be disabled by the latter when saidbail is encountered by any of said disks in the movement of theaccumulating mechanism, whereby the ribbon is moved for the printing ofthe first item in case the register is clear, and is left stationary forthe printing of the items after the first.

3. In an adding and recording machine, the combination of adding wheelshaving a movable frame,'a movable support for a two-color ribbon, a pairof levers for shifting said support, a-second pair of levers, a I

shaft on which said second pair of levers are fixed, means for actuatingsaid shaft from the driving mechanism of the machine, a bail arranged tobe actuated by the said frame of the adding wheels, pawls constructed tocorn meet or disconnect said airs of levers and controlled by said bail,disks carried by said adding wheels and having notches which arepresented to the bail when all of the adding wheels are at zeroposition, and means carried by the bail for entering said notches toleave the bail stationary at such time, and also engageable by saiddisks to move the bail and disconnect the pawls when any of the addingwheels is not at zero position.

4. In an adding and recording machine the combination of a movableaccumulator, a-

printing ribbon having a plurality of colors, a movable support for theribbon, numeral disks having notches 7, a bail 9 to enter said notcheswhen said disks are at zero position, and mechanism interposed betweensaid bail and said ribbon support, whereby the movement of theaccumulator shifts said ribbon to print a distinctive color when all ofthe numeral wheels of the accumulator are at zero and leaves said ribbonunshifted to print the usual color when one or more of said disks is notat zero. 7

5. In an adding machine the combination of a movable accumulatorcomprising numeral wheels, actuators for turning said wheels, disks onsaid Wheels and having notches which are in alinement When said Wheelsare at zero, a movable bail having means to enter said notches, ashiftable carrier for a printing ribbon having a distinctive color,shifting means ,for said ribbon carrier, and pawls for operating saidshifting means to bring the distinctive part of the ribbon to printingposition and engaging said bail and movable by said bail to inoperativeposition. Y

' 6. In an adding and recording machine the combination of a movableaccumulator, a shiftable support for a ribbon inked in a distinctivecolor, and means controlled by the movement of the accumulator forshifting the ribbon support to bring the distinctive part of the ribbonto printing position when the parts of the accumulator are at zero orclear position.

In testimony whereof I aflix my signature.
